Arrhythmogenic right ventricular dysplasia is a cardiomyopathy of genetic origin characterized by predominant right ventricular involvement, episodes of ventricular arrhythmias with an increased risk of sudden death.

We report the case of a 20-year-old asymptomatic professional soldier who consulted for an annual check-up. The electrocardiogram revealed an abrasion of the anteroseptal R wave, persistent S wave in V5 and V6, an S1S2S3 pattern and negative T waves in the anterior and inferior leads. The echocardiogram and cardiac Magnetic Resonance Imaging (MRI) revealed major criteria (RV dilatation with end diastolic volume 147 ml, global RV hypokinesia and dyskinesia located at the basal and apical inferoseptal wall) confirming the diagnosis of arrhythmogenic right ventricular dysplasia. Also, dense fibrosis was seen in the interventricular septum and the basal anterior and lateral walls of the Left Ventricle (LV) suggesting biventricular involvement.

The patient remained asymptomatic after one year without treatment. This clinical case highlights the importance of imaging in the diagnosis of rare cardiovascular diseases such as biventricular arrhythmogenic dysplasia.
